"Long ago, in the largest canyon system in our solar system, vibrations from ""marsquakes"" shook soft sediments that had accumulated in Martian lakes. The shaken sediments formed features that now appear as a series of low hills apparent in a geological map based on new NASA images. Enhanced color image of the Candor Colles region of Candor Chasma, Mars. Image is 1 km (0.62 miles) across. (USGS Astrogeology Science Center, Flagstaff, Arizona)"
